SUMMARY:Probing the primordial universe with high-resolution CMB and g
 alaxy surveys\, Astronomy Colloquium\, Moritz Muenchmeyer\, UW Madison
DESCRIPTION:The big bang can be viewed as a massive cosmological parti
 cle collider\, whose output is the matter and radiation distribution t
 hat developed into the universe we observe today. By measuring the mat
 ter distribution of the universe more precisely\, we can in principle 
 learn more about the ultra-high energy physics of the early universe (
 inflation). However\, extracting this primordial information is very d
 ifficult because of the complicated non-linear physics of structure fo
 rmation. In this talk I will describe current and upcoming experiments
 \, in particular focusing on secondary CMB anisotropies and galaxy sur
 vey data. I will show some recent ideas how their data can be used for
  primordial physics\, and describe how modern computational methods fr
 om machine learning help to deal with non-linear physics. <br>
